Abstract
In a method (M) to detect a noise signal (PS1, PS2, PS3) in a digital audio signal (EAS), it is provided that the audio signal (EAS) is divided into successive signal sections (SAS), and the energy contents of successive signal sections (SAS) are determined, and the energy contents of a signal section (SAS) are evaluated in relation to an energy threshold (ET), and that the occurrence of at least one high-energy signal section having an energy content above the energy threshold (ET), and the occurrence of at least one signal section (SAS) preceding the at least one high-energy signal section and having an energy content below the energy threshold (ET), and the occurrence of at least one signal section (SAS) following the at least one high-energy signal section and having an energy content below the energy threshold (ET) are detected, and that a quantity of signal sections (SAS) that precede the at least one high-energy signal section and a quantity of high-energy signal sections and a quantity of signal sections (SAS) that follow the high-energy signal section are counted.
